Selstack is a platform for creators and businesses to build a public selling page, share individual offers, accept supported payments and bookings, and manage the resulting orders and customer details. A “Stack” is a selling page. This guide explains the relevant workflow and the seller’s responsibilities; payment methods, account requirements and some features depend on the business configuration and plan.
This task changes what a customer sees or can buy on a public Selstack journey. This guide focuses on how to prepare and upload genuine media, order the gallery and inspect every image in the responsive and full-screen views.
Prepare the source image first
The current Stack editor accepts up to ten images or videos but does not provide manual cropping or a per-image alternative-text field. Crop and export the source file before upload when composition matters.
Upload and order the gallery
Use Add images or videos, wait for each asset to appear and place the clearest asset first. Use only owned or licensed media that accurately represents the offer.
Check responsive presentation
Review the editor preview and the signed-out public link on mobile and desktop. Use View full image and the previous or next controls to inspect every image at full size.
Replace a poor crop
If the responsive frame hides essential detail, edit the source image to add safe space or use a different aspect ratio, then replace it. Do not look for a crop control that does not exist.
Troubleshoot loading or flicker
Confirm the file type and size, refresh once and try the public gallery again. If one asset consistently fails while others work, replace that source file and report the safe offer reference if the problem remains.
Example: Upload and Check Product Images
For a book, upload a clean cover, contents spread and back cover; View full image should let a visitor move through all three.
If Upload and Check Product Images is not working
If text is cut off, prepare a source image with more edge spacing and replace it because Selstack has no manual crop control.
Confirm the result
- Title, media, price, currency, fields and fulfilment details describe the same offer.
- The selected access and delivery options match what happens next.
- The signed-out mobile page shows the complete action without clipping.
- Only a ready, available offer is public.
When to ask Selstack for help
Give customers a useful view of the offer
Images on a Selstack selling page help visitors understand the product before they decide whether to buy. They should support the written description with information about appearance, contents, scale and condition. A photograph cannot answer every question, so explain important details in text as well. For a digital product, show an accurate cover or a representative preview. For a physical item, show the version the customer will receive. For a service, choose a relevant image that helps explain the work without implying a result you cannot promise.
Plan the images before uploading
Choose a clear main image and a small set of supporting views. The first image should make sense when someone encounters the offer without any previous conversation with the seller. Supporting images can show another angle, a close-up, packaging, included items or a practical use. Avoid uploading several nearly identical photographs simply because space is available. Each view should answer a different customer question. Remove images of old versions or unavailable options, and check that visible labels match the title and description of the current offer.
Make the subject easy to recognise
Use even lighting and a background that does not compete with the subject. Keep the item in focus and leave enough space around its edges for different card shapes. A simple photograph taken carefully can be more useful than an elaborate composition that hides important details. If colour, texture or small fittings affect a purchase, include a closer view. Do not use heavy editing to conceal damage or change the apparent contents. Where scale could be misunderstood, give dimensions in the description rather than relying on a prop in the photograph.
Use the editor's image controls deliberately
Add the intended files through the offer's media controls, then inspect the uploaded result. Arrange the gallery so its first view explains the offer and subsequent views develop that explanation. Where the editor provides a featured-image choice, confirm the correct asset is selected. If a crop control is available, keep the important subject within the visible area. A successful upload is only the beginning of the check: the card, full offer page and larger image view may present the same source differently. Review each relevant view before publishing the change.
Keep important words outside the picture
A customer should be able to understand the offer even when an image loads slowly or is difficult to read on a small screen. Put the product name, quantity, price context and delivery details in the appropriate text fields. Avoid making a promotional poster the only explanation of what is being sold. Text inside a wide graphic often becomes too small when the graphic is reduced to a phone card. If an illustration contains essential instructions, repeat those instructions clearly in the description so the customer does not need to zoom and interpret them.
Check rights and customer expectations
Upload photographs or artwork you created, own, or have permission to use for this purpose. A picture available through a search engine is not automatically free for business use. Stock photography can illustrate a topic or service setting, but it should not misrepresent the actual product, seller or customer experience. Do not imply that a person pictured has bought or endorsed the offer. If the exact item is important to the decision, use an accurate product photograph and explain any meaningful differences between the example shown and the customer's order.
Review on a phone and a larger screen
Open the offer through the public URL and inspect the main image, gallery controls and any larger-image view available to visitors. On a phone, check whether the subject remains visible without sideways page scrolling. On a larger screen, check whether the image is sharp enough for the size at which it appears. Move through the gallery in the intended order. A visitor should not need to guess whether a supporting image belongs to the same product. Ask a colleague to describe what they think is included using only the page.
Maintain the gallery as the offer changes
Update images when the product, packaging or included material changes. Keep the media, written description and available options consistent so customers do not have to resolve contradictions themselves. After saving, reopen the public link and confirm the expected version appears. If an image is missing, check the selected asset and its saved state before repeatedly uploading replacements. When asking support for help, provide the relevant offer reference and describe which view differs from the editor. Keep original source files somewhere the business can find them for future updates.
