[Seaside] Suggestion: WAFile subclass: #WAImage for image uploads

[Dmitry Dorofeev]

Hi all,

I think it would be nice to have image height, width and type (GIF,JPG 
or PNG) as 3
additional methods in the WAImage class. And special call like this:
		html imageUploadWithCallback: [:f| .....
to specify that we want to get only images and f will be WAImage 
instance.
I think we should get exception if user uploaded wrong file (corrupted 
or not supported image).
That would support very common task of image uploads and saving 
height/width elsewhere for later HTML generation.

I have written a code to parse images in GIF/PNG/JPG and detect their 
height/width. Should i try
and change Seaside Classes (note: i am Smalltalk newbie) or should i 
just send my code as i have it now
in hope that someone more advanced will implement it?

Hope you all agree that we need WAImage in Seaside and avi will 
integrate this suggestion somehow.

Thank you!

-Dmitry.
