It works if I specify a custom crop size string. If I leave that blank in the Image field, AND turn on “Open cropper by default”, default aspect ratios show up, and that’s when I get the error when I click the Save button. If specific crops need to be set before cropping can work, maybe add some error checking to prevent people from leaving the crop settings blank and also turning on “Open cropper by default”?
I’m beginning to see how the crop function works, and what to do with it, so this is looking pretty cool!
Is there any way to specify a crop that is the original ratio? I want the medium size to be the same ratio as original for starters. Or, is there some way to make Original the default aspect in the cropping tool instead of Free? Also, is there some way to make a crop for one size fill the whole image to start, instead of starting off cropping the image?
One thing that would make this more user-friendly:
When I insert an image and the cropping tool opens, I expect to be able to create the three crops (or however many I have specified) and then click the Save button to save them all. The thumbnails on the left get created automatically, whether or not I have save each crop, so it looks like I’m saving a whole set. If each crop HAS to be created separately, maybe don’t display thumbnails on the left until a crop for that size has been saved?
ALSO, it would be great to be able to make certain settings required. For example, I want editors to always enter alt tags for images to satisfy accessibility requirements.
