When you upload a product image in Acenda, our image service automatically creates the sizes each sales channel needs — you don’t need to pre-crop or resize anything yourself. This article covers where to manage your images, what to know about file requirements, how marketplaces use the images you upload, and how to troubleshoot common issues.
Where to manage your images
Product images live on each item’s own page, not in a separate images tool.
In the sidebar, under CATALOG, click Items.
Click the eye icon next to the product you want to update.
Open the Details tab and scroll to the Media section.
Click the pencil icon, then Upload Image (from your computer) or Add from URL (paste a direct link to the image file).
Drag images to reorder them, and set each one’s Type to main or alternate.
Click the Save Changes icon to save.
Updating a lot of items? See Bulk Updating Product Images in Acenda instead of editing items one at a time.
Image file guidelines
A few practical guidelines for the files you upload:
File size: keep uploads under 25 MB. Larger files can fail to process.
File type: JPG or PNG display correctly everywhere and are the safest choice. We can’t guarantee how every channel handles other formats.
Resolution: Acenda can generate image variants as large as 2000×2000 px, so a source image around that size (or larger) gives channels the best version to work with, especially for zoom and gallery views. A smaller source image still works, it just won’t look as sharp when a channel displays it larger.
Acenda stores and serves your images itself — you don’t need a separate image CDN. If you’re linking to images with Add from URL or an import file, Acenda automatically converts standard Dropbox and Google Drive share links into direct-download links, so you can paste the normal sharing link as-is.
Looking to host supporting files like size charts or instruction manuals instead of product photos? Use CATALOG > Assets — see How to use Acenda to Host Size Charts and Instruction Manuals.
How marketplaces use your images
Each marketplace has its own rules for how many images it accepts and where they come from. For example, on Target+:
Acenda sends the main image plus up to 15 alternate images, in the order they appear in Acenda.
Alternate images come from each variant. A parent (non-variant) listing sends only its main image.
If an item has no image set as main, Acenda automatically uses its first image as the main image.
Other channels have their own limits on image count, format, and background. Check the specific channel’s own requirements, and watch Item Issues (under CHANNELS) for any image-related rejection.
Troubleshooting
Target+ error: “Image may contain sensitive material”: this is Target’s own automated review, not an Acenda check — false positives are common. In Item Issues, the Attribute Path column tells you which photo was flagged (Main Image or Additional Image 1, 2, and so on). See Troubleshooting Target+ Error: “MINOR_DATA_VALIDATION: Image may contain sensitive material.”
A Dropbox or Google Drive link won’t import: make sure the link is set to share with “anyone with the link.” Acenda converts the normal sharing link automatically, so you shouldn’t need to edit it — but if it still fails, grab the file’s direct-download link yourself and use that instead.
Images are in the wrong order on a channel: drag to reorder them in the Media section and confirm each image’s Type (main vs. alternate) is set correctly, then save.
A new or updated image isn’t showing on a channel yet: images are processed before they’re sent out, so there can be a short delay between uploading a change and seeing it reflected on a channel.
