Hello and welcome to the forum
Strange one this?Yep, tried that too! Get the "Up Loading" image, then tells me "There is a problem, the image is too large" (Tried the 1.1M image this time.)???? URGH!!!!!
PNG, file types ending in .png
PNG stands for Portable Network Graphics. It was created as an open format to replace GIF, because the patent for GIF was owned by one company and nobody else wanted to pay licensing fees. It also allows for a full range of color and better compression.
It’s used almost exclusively for web images, never for print images. For photographs, PNG is not as good as JPEG, because it creates a larger file. But for images with some text, or line art, it’s better, because the images look less “bitmappy.”
This is what I do and its JPG.....
Raw image files
Raw image files contain data from a digital camera (usually). The files are called raw because they haven’t been processed and therefore can’t be edited or printed yet. There are a lot of different raw formats–each camera company often has its own proprietary format.
Raw files usually contain a vast amount of data that is uncompressed. Because of this, the size of a raw file is extremely large. Usually they are converted to TIFF before editing and color-correcting.
JPEG files are images that have been compressed to store a lot of information in a small-size file. Most digital cameras store photos in JPEG format, because then you can take more photos on one camera card than you can with other formats.
A JPEG is compressed in a way that loses some of the image detail during the compression in order to make the file small (and thus called “lossy” compression).
JPEG files are usually used for photographs on the web, because they create a small file that is easily loaded on a web page and also looks good.
JPEG files are bad for line drawings or logos or graphics, as the compression makes them look “bitmappy” (jagged lines instead of straight ones).

Here endeth the lesson?
Hmmm, this is really odd as I initially thought it was PNG files that were the issue, but just uploaded this PNG which is nearly 4MB (although compresses to 1.1MB on upload). Clearly not that then! Can you email me a copy of the image so I can have a look and see if there is something weird with the format? gazhyde@zroadster.org

Hi and welcome from me in Scotland
The thought of participating in a lap of Silverstone is attractive, but I've been up to Silverstone and Gaydon in the past few weeks and tired of traversing the A34.Forget Beaulieu we have a parade lap round Silverstone EPIC
Thank you for the welcome.Hi and welcome from me in Scotland
Thank you. Very 'atmospheric' photograph! Rather beyond my technical competence.Hi from me in South Yorkshire
