They are very small too.
To shrink pictures you may want to try to use xnview.
Here is a small tutorial that I made recently and posted elsewhere:
Launch the program, browse to the folder in which are your files, select all files, go to "Tools" menu -> "Batch processing".
It should then list in that window all the files that you selected at the step before.
Possibly adjust the output directory (here I have set same as input, "e:\01" which is my temp folder), select JPEG as format, click "options" on the right
If your pictures are already in JPEG format, I recommend to select another directory as output, so you can make few tries (else your original images will be overwritten, and if you put a wrong setting they are lost)
adjust the slider to have quality set at 80 instead of default (95?), enable the "progressive" option (makes a little smaller files), then "ok".
Back in the "batch processing" window, now open the "transformations" tab/page.
If your pictures have back borders you'll have to use the "crop" action - tell me if you need info about that, I can add these
To resize the pics if they are bigger than 720 pixels wide (which is the case with PowerDVD if I am right), select the "resize" action and click "add" :
Enter 720 in the "width" field.
If the ratio is already good (i.e. pictures are not too flat or too high) you do not have to fill the "height" field, and just keep the "keep ratio" option.
Else you have to uncheck that option and enter the right height depending on the movie.
Height = Width / ratio, with ratio being one of the following in most of the cases:
1.25 (some very old stuff)
1.33 (fullscreen tv)
1.66 (some tv series)
1.77 (widescreen 16:9 tv, usually matches images with black border, not common on pictures where black borders are already removed)
1.85 (movies)
2.35 (movies)
Click "go" and you should get your images converted
Uncheck the "close..." option just above the "go" button if you want to make few tries without re-entering settings each time.
Here I mentioned 720 as width to enter because it was about DVD pictures.
For lower quality pictures you may enter 640 for example, no need to make too big pictures if they are not so sharp.
