Is there a maximum size for a Cover Scan contribution?

The rules are unclear to me if there's a maximum size for a Cover Scan contribution.  Should I be limiting them to 300Kb, or so?  Or can I submit a monster-size file in the interest of clarity?  My guess is that it might be reduced in size before being released, anyway, but it would still remain somewhat clear.

There is no Dimensional limit, but anything over 500x700 pixels will get resized down to that by Invelos when it gets approved. Each scan has a maximum file size of 200Kb. I find that you have to compress a 500x700 pixel image between 9-15% to get under 200Kb.

The maximum file size is 200,000 bytes.  If you submit something larger than that, it will be automatically compressed and downsized when submitted.  And, while this automated compression is done fairly well, it is not as good as many, more powerful tools you may use on your own PC.

Also, even if a file is the right size, when you import it into DVDP, it gets modified by the application.  So, if you want to have complete control over image compression and quality, you need to save it directly into the images directory, named appropriately.  Then, the application will use the new image, as you saved it.  And when you upload, it will be exactly as you saved it, too.  Unless it is over 500 wide, 700 tall, or 200,000 bytes.  (mind you, that's 200,000 bytes and NOT 200Kb.)

I haven't spent a lot of time testing the limits, but I believe the limit is 200kb (meaning it's ~195,000 bytes).  I'm pretty sure that I've had a few covers that were 197,000ish bytes and when I contributed them I could tell they'd been compressed.  I brought them down to 194,000 or so and then they uploaded without any loss in quality.  This was several months ago so my memory may be a bit fuzzy.

Nope.  They can definately be over 195,000.  I've had some that were higher and were uncompressed by the upload.  For instance, 669198094194.  The front cover image is 199,971 bytes.

The really odd thing is that I have one image in my images folder, which was pulled from the online, which is 343,307 bytes!  How'd that happen?  Sku for that is 631595050226, in case anybody wants to look.  The back cover is the large one.  Weird.

Also, for the record, 200Kb is actually 204,800 bytes.

Everyone above is correct...500x700 by 200,000 bytes is the largest image file size DVDp retains.

However, you can submit any size you want.  At submission time at the receiving end the file is reduced to fit the above limits.  DVDp algorithm for compressing them isn't bad but i prefer to maintain control over the image so i reduce it to within those limits before submitting (and save a larger, uncompressed image for local use)
Bad movie?  You're soaking in it!

The limit is 200,000 bytes, not 200k or 204,800 bytes.  Any image over this 200,000 byte limit is recompressed.  (It's also 195.3k and Windows will either say 195k or 196k - Vista can say both at the same time!)

If you want to optimize your contributed cover, resize it to no greater than 500 pixels wide and 700 pixels high and 195k.  Save it at the highest quality JPeg setting and take a look at the resulting file size.  If it's above 195k, drop down the quality a notch and repeat until it is below 195k.  If it is exactly 195k, view the properties of the file to see the byte count.

has been mentioned before, but not in this thread (at least that i read) and it's an important part some may not catch.

500x700 is max in either direction. So if your cover is 510x700 it will be resized to 500x600 something

also, i beleive dvd profiler does this, but in most programs you have the option to do it or not, but to constrain proportions so the image doesn't get distorted

*edit* just wanted to add, that I just checked with a duplicate file checker, and loading the cover images through dvd profiler (even if they start within the size limits) it does recompress them. my poor eyesight visually not much difference, size wise however was about 86KB

You can adjust the compression ratio in the cover editor - but this isn't the same compression that happens when you upload a scan.  That happens on Invelos's server.  So if you scan in a very large cover and paste it into DVDP, it gets compressed on saving - and you can adjust it to use the best possible quality compression which will result in a very large file.  Then if you submit the cover scan, it gets recompressed again to bring it down to within the 500x700x195k thresholds.

I've recently seem some old covers in the database that measured 500 x 721 and 500 x 743, so 700 tall must not always be the absolute.

Yep, that one I mentioned above (UPC 631595050226) is actually 772 x 1825 and 343,307 bytes!  I'm not sure how such a large image snuck through, but there's no denying that it's there!  Weird.

Oh... that's one of mine....   

In the first days of Invelos operation, during The Great Contribution Storm, I noticed an intermittent bug with the submission system; a few profiles my local hi-rez scans went up without being rescaled!  Of the 400 or so I probably touched, I recall maybe three had this circumstance...  (guess that one hasn't been replaced yet) 
Probably others we affected as well, or maybe some of the other odd dimensions came in with the import of IVS data.
