This is the silliest requirment I have seen in 10 years. I can see this tiny size requirment being an issue when we had modem over telephone speeds and disk space was much more expensive but this is laughable.And why is the size limit so small for these submissions when all the others are larger? Are the site operatators aware of this?

The contest limit is not 16kb.

The contest size requirements are here:
https://www.modelmayhem.com/education/s … tent_rules

Any images uploaded to Model Mayhem should follow these size guidelines:

Photo Size, in pixels:
No less than 200 wide and 300 high
No more than 16 million total pixels (eg, 4,000 wide by 4,000 high)
File Size, in kb:
No less than 7kb
No more than 1500kb

I have gotten that same message you are referring, but it's been a while so I don't remember what turned out to be the formal issue.  It might have been that I had one dimension over 4,000 pixels?  I recommend you use the Contact a Moderator feature to the the formal answer from IT.  I tried to search for the answer for you but unfortunately I wasn't able to find it.  I will update here if I'm able to find it.

I've taken this IT response from a CAM someone else sent in about this same question:

Can you check the file size of your image? It should be between 7kb and 1MB in size. You'll also want to check the pixel size of your image - this should be no smaller than 200 x 300 pixel and no larger than 4 million square pixels. You should be able to find this information when checking the properties of the image on your computer.

Please note that your image must meet both the file and pixel size in order to be uploaded.

You will also need to double check your file type - Model Mayhem can only accept .jpg and .png file types.

Finally, if your image meets these requirements and still does not want to upload, please let us know.

If your images are too large, you may need to resize them. Unfortunately Model Mayhem does not offer any resizing tools.

The best way to resize photos is with a an image editing software on your computer, such as Paint, GIMP, Photoshop, etc.

If you don't have image editing software on your computer, you can use one of these online utilities. There are more online if you search, but these do give you some options.

We recommend that you resize your photos to be 1000 pixels wide or less.

If you have any more questions please let us know!

I got that exact message when I tried to submit to the POTD18+ contest.  16kb is ludicrously small (even for the days of dialup modems) so I assumed it had to be wrong and instead shrunk my photo down from 3000kb until it was magically accepted.

I didn't know the actual requirements, so it'd be nice if the message were corrected.  (I suspect it's supposed to say "no more than 1600 kb" though it appears the actual requirement is 1500...)

As above, the size guidelines are as follows:
Photo Size, in pixels:
No less than 200 wide and 300 high
No more than 16 million total pixels (eg, 4,000 wide by 4,000 high)
File Size, in kb:
No less than 7kb
No more than 1500kb

I do not have the ability to correct the error message.  It is known about and hopefully IT does have a ticket in for that, but it would be difficult for me to confirm as I'm not in the IT side of things.  I do agree it's very difficult to have the error message be unhelpful.

This is just how I do it, but you can decide for yourself if you think it's the best method. If you're using Photoshop, when you go to export your JPEG, set the longest side to 1500px and set your quality to 7 (highest). If your size is showing around 760Kb or lower, it should be okay. If it's over 760Kb, I then start dropping the longest side down by 50px until I'm under 750Kb.

Personally, I think the 7 quality setting over the 6 does look better to me. I can see more detail in the images, so I'd prefer to lower the resolution a bit, but still export at the highest quality setting.

Again, this is just my suggestion, but I think my images look pretty good on the site when comparing them to others in the contests. If some members have alternate ways of doing it, I'd be interested in hearing them.
