Thread: Image upload not working on forum.pjrc.com

  1. #1

    Image upload not working on forum.pjrc.com

    I found out that image uploading is not currently working for me on ANY devices incl. smartphones.

    I'm using Google Chrome.

    Only upload from URL works.

    Click image for larger version.

    If the image to upload exceeds some size ( 1GB ? ) it will cause a fail with no note as to why.

    File types & maximum sizes

    Info from the "Manage Attachments" page (apologies for the formatting - conversion from tab-delimited to spaced is not so straightforward !!):

    Code:

    May be a good candidate for a wiki entry . . .

    I think those limits for file sizes are way too low. Typical limit for an image is 5MB. If exceeded, warning message should appear with precise reason.

    Lots of good information on the Teensy family of devices is available in the Teensy Wiki <https://github.com/TeensyUser/doc/wiki> . . . my previous comment referred to my thinking that these upload limits might be mentioned in there somewhere. However, maybe it would be more appropriate to list them in the FAQ for this forum, as they don't really have anything to do specifically with the Teensy.

    Adding to that github Teensy WIKI is a good thing. PJRC wiki been needed a long time - but small company priorities - making hardware and designing new and shipping eats up time - then things like months of this shutdown without full staffing make it harder.

    ... not sure those numbers are all correct? It seems an image near 1GB is accepted. But if an upload fails it is likely due to size.

    I think the file size numbers in the list are wrong but image size in pixels is right. I have to go resize to upload photos. It does seems a bit 20th century in it's limits - even 3 generation old phone cameras produce > 1 Mpix images
