questions about new image resizer
Design and Skin Customization
Hi SE
The image resizer only works on images uploaded with JR items, i.e.. Audio, Blog, Event, File, Gallery, Group, MySites, Profile, Store and User modules. It does not work on images embedded in comments and posts (as imported from Ning, say) as these are referenced images and somewhat out of JR's control!!
Difficult to recommend a maximum size as peoples' perception of image quality varies. However, this tool was recently used on a photography based site and a max size of 1536px was deemed by their expert as sufficient and the process reduced their disk usage by about 70%, which was pretty significant (YMMV, of course)!!
Remember though, that once images have been resized, there's no going back.
