Why a limit of 256KiB on uploads to this forum ?

Post by nurber »

This is a difficult size restriction that on more than one occasion has prevented me and subsequently discouraged me from posting. I've posted about at at least once and I see at least one other, but never an acknowledgement from Pico ?

The attachment limit is set to 10M and I have seen attachments at that size. So not sure on what your issue is.

The forum software has just been updated as it was many versions out of date, so if you can give specific details of the issue, and steps to reproduce it, we can take a look.

Thanks for reply Martyn. Just now I tried to upload a 496KiB image ( .png supported ? ) and the upload progress meter moved as it should, but no upload and no message. I'm using latest Chrome. If certain formats supported is there a document that says which ?

png is a supported format. I carried out a test using WIndows 10 Snipping Tool to create a full screen png image which was only 100KiB and attached that successfully. As did a PicoScope 6 entire Screen capture which is only 71KiB.

What are the png images of ?

It works a little bit strange (chrome) not tested in IE

After uploading the .png it looks like nothing happened.
Then clicking preview after upload you can inline the image.
It looks like in (chrome at least) you need to click preview to see the uploaded image and the button to place it inline.

Converted above png of 140k to .jpg and back to .png then it was 1.4MB and it wont upload see below screenshot.

Thanks for follow-up Bennog. Windows screenshots are .png format and I don't feel I should have to convert to post to forum ( assuming it made a difference ). I had to crop these 500KB screenshots(1920x1028) because this forum interface reports "File too large: Screenshot (5).png". What good is a forum with such a constraint preventing people from uploading the most communicative piece of information possible ? (A .psdata file is too much work for some between downloading file, loading Picoscope and then massaging the data to get to the waveform portion/glitch/etc. that person is trying to communicate.)

just happened to me again so I attach a screenshot of the error message from trying to attach a 455KB png file. This message is in my opinion coming from the server and not a product of the browser in use.

Hi Martyn. The two attached png files don't exceed 250KB so I can't confirm the increase you just posted about, but can you confirm 10M limit mentioned above as I just tried posting a 9MB psdata with the same "File too large" error. See attached for screenshots of error and file attributes.

The forum limit is 20MB for file attachments, so there must be something in the backend php or website caching that is causing an occasional issue as others have successfully posted large files. I will ask the IT team to take a look.
