  2. Our gif only content threads have a rule where all thumbs must be posted as a static thumbnail that does not play. Currently imagebam made a change where they no longer produce static thumbs. Therefore, please do not use imagebam, or any host, that provides live playing gifs in those specific threads. If you see your gif playing once you post, try to use a smaller thumbnail and if that does not work use a different approved host.

    I notice some folk on Phun describe the definition or "quality" of the pictures they post by specifying the actual pixel size (4k, 2048, etc.), whereas others refer to them as HQ, VHQ, UHQ, etc.. Is there a specification somewhere, if not in the wide world then at least on Phun, that relates the two methods to each other?

    No,there isn't S.,and it's not a must to post it,more a service from the thread starter (a lot of model sites are offering different res) ;-)

    When i post a HQ,UHQ,etc. in my titles,i mostly talk about the filesize,also meant as a warning to members with very slow connections not to click the thumbs.

    For me HQ ~ 500-1000 KB
    UHQ/VHQ ~1MB & bigger
    VUHQ 3MB & bigger

    I thought it was the resolution that matters,as the same resolution can have different size according to the compression.I for myself think UHQ for res over 2000 pxls ;)

    aside the fact that for me neither screen-size (pixel/inch/cm) nor resolution (dpi) isn´t automatically a criterion for quality (-> content, execution, procession etc.)

    it appears to me that here xxxQ means screen-size, a pretty familiar distinction on many websites (small, medium, large, extra large).
    there are sites with extra-large pics (~3000x6000) with a high resolution (100dpi) - average filesize of 5-7MB - not to mention some .raw-"collectors-editions" from metart (~20MB/pic).

    a blown up mag-scan doesn´t have to be of better quality than a smaller, web-published pic. most times it´s exactly the opposite.

    When i convert a 100 KB .jpg to a 2.5MB .bmp,thats for sure not an UHQ (and it would not be tolerated),but that goes without saying IMHO.
    When i post a UHQ in my titles it is at least at 2-4k pixels ;-)

    I think "quality" is debatable, as River suggests, and definition does not relate to image size - several sets I've seen recently comprised massive-sized JPG files (7k pixels on a side) but where the pictures themselves were either grainy or unfocused (or both), and consequently low optical definition!

    But I think we could usefully have an in-house specification of image size ranges - these at least are indisputable!
