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.
Selstack currently fits uploaded media into responsive previews; it does not provide a manual crop or per-image alternative-text field in the Stack editor. Prepare the crop before upload, then use the preview and full-image viewer to check the result.
Follow the workflow
- Step 1: Open the offer editor and locate the image upload control.
- Step 2: Prepare a clear JPG, PNG or WebP that shows the real product or an accurate digital preview. Crop it in your image editor first if the important subject is too close to an edge.
- Step 3: Upload up to ten supported images or videos and put the strongest, clearest asset first.
- Step 4: Preview on mobile and desktop. Open View full image, then use the previous and next controls when the offer has more than one image.
Confirm the result
Check sharpness, ownership, prepared crop, gallery order and mobile loading.
Important: Do not embed essential terms only inside an image or upload artwork you do not have permission to use. If a crop is wrong, replace the source image; there is no manual crop control in Selstack today.

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.
