Vome uses two kinds of branding image. A cover photo is the wide banner across the top of a page. A logo is the small square or circular mark that identifies your organization.
This article lists every place you can upload one, the dimensions that actually apply, the formats that work, and which places keep the resolution of the file you upload. It is written for administrators.
Seven places.
Three places.
Because there is no separate logo for those.
The circle you see at the top of a form page or an opportunity page is your organization logo, or your site logo if that form or opportunity is linked to a site. Categories have a cover photo only.
So if you want to change that circle, change it on your organization page or on the site, and it updates everywhere it appears. There is no upload button on the form or the opportunity itself, and that is deliberate rather than something missing.
At least 820 pixels wide by 312 pixels tall.
Your organization page, your categories, your opportunities and your forms enforce this. Anything smaller is rejected with a message asking for those dimensions.
That is a ratio of roughly 2.6 to 1, so a wide landscape image rather than a square one. A good target is 1640 by 624, which is the same shape at twice the size.
Sites, groups and page layout sections do not check the dimensions, but they display the image in the same wide band, so use the same size there.
A logo is cropped to a square, so start with a square image. 400 by 400 is plenty. Your organization logo is saved at 194 by 194, so a much larger file is scaled down and gains you nothing.
Profile photos, for administrators and for users, are cropped to a circle and saved at up to 800 by 800. Here a larger square file does help, so 800 by 800 is a good target.
It depends where you upload it, and this catches people out.
Resolution is kept on sites, groups, categories, course images, award images and page layout sections. A larger file does give a sharper result in those places.
The file is re-rendered on your organization page cover, on opportunity covers and on form covers. Those three open a cropping tool, and the result is saved at 812 by 312 whatever you started from. A 4000 pixel wide photo produces the same file as a 1640 pixel wide one.
The practical advice is the same either way: start comfortably above the 820 minimum so you have room to crop, and do not bother going far beyond 1640.
Use JPG or PNG. Both work in every place listed above.
Most of the uploaders accept only JPG and PNG. A few of them (course images, award images and page layout sections) accept any format your browser can read, including WEBP, but there is no benefit to using one, and sticking to JPG and PNG keeps the same file usable everywhere.
Choose PNG for a logo, especially one with a transparent background. Choose JPG for photographs.
One thing to know about categories: a category cover photo is saved as a JPEG once you crop it, so transparency is lost. Use a photograph there rather than a transparent graphic.
Keep cover photos and logos under about 2 MB.
A heavier file does not look any better once it is on the page, and it slows down every page it appears on, including the pages your users see before they apply. If you are exporting from a design tool, the "web" or "screen" quality setting is usually enough.
That depends on whether the place you are uploading to crops or fits.
Your organization page cover, opportunity covers and form covers open a cropping tool. Drag and zoom until the important part of the image sits inside the frame, then save. Nothing is cut off without you seeing it first.
Sites, groups, courses and awards do not crop. They fit your image into the space available, which means a tall or square image can end up with empty bars beside it. A wide image avoids that.
A logo is always cropped to a square or a circle, so anything sitting in the corners of a non-square image will be cut off. Leave a little breathing room around a wordmark.
Both are optional, and both display small.
