Thanks for raising this question around the image rendering size in the Jive Photo Album plugin. You are correct that images will be resized upon clicking to fit an optimal width. Unfortunately, due to JIRA bug JIVE-63028, small photos may be upscaled too much, causing pixelation. This is noted as addressed in Jive 8.0.3, so in the meantime, I would encourage either uploading only larger images (width of > 600px) or inserted a white border around the image to increase it's width. Here's an example of a 97px x 59px image:
When uploaded into the a photo album, it looks like this:
Now I went and added white boarders to it, making it 600px x 60px:
And then re-uploaded it alongside the first:
So while this may not be ideal, it will provide power users an option to workaround the distortion until you're able to upgrade to Jive 8.0.3+.
Let me know if you have any other questions on this.
Thank you Jeph for the quick response.
This is very useful and I will advise our end users accordingly
