Don't ask me why my pic attaches and comes out sideways - all of them apparently do that... Don't know why.
Not
all, just (some

) of yours & a few others...
That's 'most likely' cos you're taking your pics in
Portrait Mode on your phone/camera, & your phone/camera is assigning the
Top Right corner in Portrait Mode as the picture's '
anchor point' & retaining that anchor point whatever orientation you actually take the pic in....

. For whatever it's worth (and btw, we
can't change this!

) the Forum's Platform Software uses the
Top LEFT corner of any pics loaded &/or displayed as it's anchor point, so when you load your pics up into a post, the Forum displays them with their anchor point in the
Top LEFT corner.... and with yours having a top right anchor point, it rotates them 90° to put that in the top left corner as the platform software specifies and we see them sideways as shown in your post #42 :banghead:
Simple fix - when you take a pic for the Forum, take it in
Landscape Mode by dropping the top of your phone/camera to the
LEFT, ie
anti-clockwise 90° so that when loaded, we see them in the same orientation (ie. correct for here/the Platform Software)

hyea:
If you upload a pic that you've taken previously in Portrait Mode & once uploaded it shows tilted 90° to the left (so it's recorded anchor point is in the top left as per the Platform Software settings

) then if you are concerned with that (most of us will manage to see the pic even if it is sideways

) you could copy the pic file into an editing suite like PhotoShop et al & either reset the Anchor Point to the pic's Top Left Corner or rotate the pic 90° in whatever direction is necessary to get it to display correctly here; then save the pic file with another name and upload
that saved file instead of your original. :thumbup:
Over to you. :cheers:
