graphics conversion

i just want to know if it is possible 2 convert an image from one
format 2 another. i thought that it would be best to find a control and load the original image and save it in the other but does there exist such a thing?? or i can use a dll, but how and wich one?? any help would be appreciated.
thanx in advance

I think a picturebox can load gifs, jpegs, bmps and pngs and save at least to bmp.

There's a DLL over at http://www.vbaccelerator.com/ that can save as JPEG too. And if you wanted a bit of a challenge, you could write a GIF saver ;)
