image converting script

[mobeets]

for each image:

• make square (optional flag, for converting images that are roughly squares to be exactly squares)
• convert to 300x300 (can be a default for icons, optional is larger)
• compress (happens automatically)

[mobeets]

convert -resize 300x img_in.png img_out.png this will convert to a width of 300px (if you want a height of 300px, you say x300 instead)

the making square thing is more subtle, so i'm just gonna not do that
