If you already have them tagged with a suitable extension, then do a
simple *.png or something like that.

Just Pass it!

You can try "file" magic

$cat > pop
#!/bin/sh
for img in $1
do
echo $img
done

$./pop "*.jpg *.png"
a.jpg
b.png
idx.png
left.png
right.png

I Use this.

#!/bin/sh

for file in *.png; do
convert \
        -geometry 550x550 \
        -quality 90 \
        -interlace Plane \
        -comment "MyCOMMENT - %f" \
        -border 2x2 \
        -bordercolor black \
        "$file" \
     "`echo $file|perl -pi -e 's|^IMG_||g'|perl -pi -e 's|JPG\$|jpg|g'`"
done
