It is a 32-bit built, so there is ~2GB address space limit. The program needs to have the pictures unpacked and if they are like 12 megapixel each, that is ~40MB in memory per picture. And then it needs another continuous chunk of memory for the whole picture. 500MB total still looks OK, so who knows... I have uploaded a 64-bit built for you to try. http://download.rw-designer.com/1.1/ImageGrid64.exe

You are right, 64-bit Windows is needed for the 64-bit version. In that case there is little I can do except trying to re-write the tool to be more efficient, which would not be easy. Displaying an error message instead of crashing would also be possible, but you still would not be able to join the images.

But it would be more professional and at least then you could give the option to reduce the number of pictures in the grid rather than losing everything.Or better still give a warning during the "edit" stage to say the number of picuters is being exceeded.

Love the rearrange button where you can cycle through layouts.

Please add some "negative" margins, or ability for custom presets,

and default filenames (templates) for easy saving.

Or dont't, it's practically perfect

I too have spent years looking for an app like this. Yours, I think, is the first of its type - and it's very simple to use and does exactly what you describe. Nice work.

Thank you so much for such an efficient tool It will be great if the tool can arrange bunch of images into grid based on their file names. Hope u will add that feature in future

can only agree to the comments above.

I like the ability to collect images from different locations, playing well together with everything search. I (as a developer) can also imagine this as a good tool to choose icons from big collections like fugue or eclipse.

here are more feature ideas... adjustable background color / order by filename/path / drag mode to copy the file from original location to target folder, maybe including resizing / more file formats (gif, bmp, ico) / saving/loading images filelists (to review the same selection/collection later again) / limit max visible number of images, then scroll

I love it, perfect perfect perfect!! :-) :-) :-) :-)
