Add JPG to Imageload

[DJDevon3]

Not sure if imageload has JPG capability. RTD is lacking details. Would very much appreciate a JPG simpletest example.

I don't believe it does. I'd recommend using jpegio.

I find it odd that every other file type can be used by imageload except for JPG. I did figure out how to use jpegio eventually which has drastically different syntax than imageload. For consistency it would be nice to have JPG in imageload. I have no idea if that's feasible, a bad idea, etc...

I didn't realize JPG wasn't in imageload when I created this request. Should I change the title to "Please add JPG to Imageload"? Is that even a valid request I have no idea.

jpeg is much more complex than the other types. I think it has been attempted before, but never successful. Maybe somebody can reverse engineer jpegio to add it?

I thought I was suggesting using jpegio in this library. I didn't mean it should be reimplemented. I just meant it could be used to provide a uniform API for loading jpg's.

[DJDevon3]

Yes, that's what I meant, if its possible. Doesn't matter if it's another layer of abstraction. The consistency for usage would be welcomed.

I'm not sure if jpegio is enabled for most boards or not. If it is, we could just add a layer to this library that calls jpegio. If not, then it may be useful to add for boards that have less flash for CP.

SWEET! 🎉
