It will convert your bmp to a jpg or any other graphic file format you choose.
Install irfanview and get all the plugins, when done, download your images to the desktop in bmp format, then fire up irfanview and have the program half screen size then simply drag and drop an image to irfanview, then from the toolbar, go to file and in the drop down box that appears select SAVE AS, then select jpg file format from the selection of file formats, to the desktop, when done, double click your NEW image to see it in the Windows picture and fax viewer.
Solution: I added the file name extension in the file name box when saving - image was a jpg obviously because it was on internet website so simply added .bmp after the name of the image in the file name box and image was saved as a bmp. Nice!
