We intentionally don’t specify any minimum or maximum resolution as our customers have clients with very different performances. High-resolution graphics actually look better but can lead to impaired performance, especially for weak clients. This is why we prefer to specify aspect ratios. You can use the aspect ratios to calculate what pixel (or cm) dimensions are needed.
What are the ideal resolutions for pictures in COYO?
With the exception of the cover pictures for pages, we have not defined any pixel specifications so far.
It is sufficient to select the correct aspect ratios for your pictures. You can see what these are for the various areas under "My teaser picture is shown distorted".
What size should page cover pictures be?
To achieve the best possible result in terms of presentation, we recommend choosing the following resolution for cover pictures: 1183x194 px.
The maximum file size for the upload is limited to 10 MB.
What does "alternative text" mean in the picture widget?
In various places, you can add alternative text to images. This text serves as an image description, which is then used by screen readers for users with visual limitations. This text serves also as a picture description that is shown when you hover over the picture with the mouse.
My picture is shown distorted/an incorrect picture section is displayed.
COYO does not compress any pictures but uses the original resolution.
A very simple workaround, in this case, is to cut the image to size beforehand. Choose the section of the picture that you want to use as a teaser picture and cut it out to the right aspect ratio in a program of your choice so that the picture is displayed correctly.
- Profile picture (avatar): 1:1
- Cover picture: 6:1
- Blog teaser picture: 1:1
- Blog widget teaser picture: 3:1
- X-Small: 20:3 (but at least a height of 120px)
- Small: 20:7
- Medium: 20:9
- Large: 10:7
The picture description is cut off in my picture gallery.
My picture is displayed landscape although it’s in portrait format.
The reason for this generally lies in what’s known as the orientation flag in the data. Modern digital cameras, cell phones, and tablets automatically detect in what orientation the picture was taken (e.g. whether the camera was turned sideways) and save this together with the actual picture in what’s known as EXIF metadata.
Modern image software reads this data and then always shows the picture the "right" way round, even if the camera was turned when the picture was taken. While "outdated" image software does not take this data into account and always shows the picture from the camera perspective.
So, there are two possible causes for this problem:
- Either the PC software takes into account/ignored the saved orientation or
- The server software (external service provider or rich text editor) ignores/takes into account this EXIF data.
I have uploaded a picture and integrated it into an article, but my colleagues can’t see the picture.
We have the documents app, which can be integrated into pages or communities and can be seen by everyone (*as long as they have the respective permission in their user role).
Pictures can also be uploaded directly into the article or e.g. into picture galleries. These pictures are automatically uploaded into the "Files" folder on the respective page/community. This folder cannot be seen or edited for a simple user. Only the admin has access here to edit the files. However, this has nothing to do with the visibility of the pictures. So, if a picture is no longer visible on a page, have the admin check whether the picture is still available or may have been accidentally deleted.
A further reason why colleagues can’t see uploaded pictures may be that the pictures have been uploaded to the user’s private file folder. This can be found on the respective user profile under "My files".
