Picture file size increases upon upload in D&D?

JazzJazz Registered User regular
I just had an odd issue in the D&D F1 thread where I went to upload a picture that is 360K in size on my PC, but appears to be 762K once uploaded, obviously then violating the D&D file size rule. I've not seen this happen before; I do have a habit of re-downloading pictures I put in D&D threads (which are usually just in the F1 thread if anywhere) to double-check the file sizes, which is how I spotted this. I have edited the post since to remove the pic.

The uploaded picture URL is here:

Honest to God, it's 360K (364K "on disc" size) on my computer.

Any ideas what might be causing this? Thanks.

    IIRC any images you upload to the forums are re-encoded. That's where the size is coming from. The size ballooning isn't super new I don't think, and I don't know if it's considered a bug.

    Like I said, I redownload the image to be doubly sure as a habit, have done many a time, and I've not seen it happen before.

    there was a bug in the past with .png uploads re-encoding using a negative compression level and having a hugely increased file size as a result, but that was fixed. Might be something similar happening with .jpg re-encoding.
