Thanks AceMan

Thats not quite what I'm looking for as there is a long wait time as the picture loads. What I'm wanting to do is to rezise the pic and save is a 50K file. Done by the program and not have use an outside program as there are diffent users and skill levels.

I have seen it done in some other access apps. I just can't seam to find the code or function for it.

Access can't do this for you. In fact, I've never seen or heard of, any program that [blue]automatically[/blue] resizes to a given byte range and saves!

Access [blue]renders[/blue] a graphic according to the [blue]Size Mode[/blue] property. Since you have large graphics, the processing time you see comes from rendering to the size of the image object (much smaller).

I wish I had better news, but I don't see you accomplishing you task unless you render the large graphics to smaller files yourself.

[blue]Your Thoughts? . . .[/blue]

See Ya! . . . . . .

The graphics will have to be presized if you want get rid of the processing time!

HI Ace and Joe

I had the same Idea as you Joe and was looking around in VB and it gave me the Idea to try some API calls. It looks like It might work from the quick test I did. I'll be giving a proper look at in the next day or so.

If you can find any program that does picture resizing, such as Microsoft Office Picture Manager, you could research if you could get it to run with command line arguments. If so, you could probably use Shell to run the program from VBA.

HI Joe before I got the API idea Last nigth I found 2 small command line utillites that resize that I thought might do the job as a back up.

Have you ever run from shell can it seen buy the user?
