I hope you'll be able to give me a bit of advice on this matter.
I've got a large number of photos, and wish to find ones that doesn't meet the minimum requirement in terms of resolution and then resize them so they do. This process should be automatic.
Any ideas?

There are many programs that can batch-resize pictures: XnView is one.
The problem is that resizing is based on width or height, not megapixels. But it's easy to do some calculations, especially if your pictures have mainly the same ratio, e.g. 4:3, 3:2, ...

But the only site that allows upsizing (from 6 MP to 8 MP) is Alamy - all other sites explicitly forbid upsizing or allow a max 5% increase; all you will get is being banned.

Do you know of any process where I can automatically filter out photos with more than a certain resolution? I wouldn't like to go through 5000 photos.

Windows 7 can do it I think.
In "my computer" (file browser) you can add a column that gives you file resolutions and then you just sort by rez.

- Put them in one or a few folders.
- Open the folder in the Windows explorer.
- Right click on the file pane title and let it show "dimensions".
- Click on "dimensions" so your files are ranked according to pixel dimensions from low to high (click again to sort from high to low).
- Select (shift-click) the first N files that are => the requirements.
- Copy those to a temp folder and upload the temp folder content.

ACDSEE
I stopped using ACDSee, since their TIFF browsing is dead slow, but what you want is built in the software. When viewing the images, select list and select some custom columns that fit your needs. Then sort by the choice, by pressing the column header.
