Hey there, so sometimes i have to rotate images in windows to get them shown correctly. And if i then upload these images to MB, there are sometimes errors and the images don’t seem to have been rotated. I am sure, that the mistake is on my side, but how can i avoid it?
So i knew it would happen again, i made a screenshot before an upload:
IrfanView can indeed rotate JPEG images in a lossless way, and it indeed needs the JPG_TRANSFORM plugin to do that. Luckily that plugin is already included in a normal install of IrfanView. To check you have the plugin: go to Help → Installed PlugIns and check if JPG_TRANSFORM.DLL is in the list.
There are other programs around as well if you google for ‘lossless jpg rotation’.
i use irfan view for most of my image editing. glad to hear, that after all these years it is still known so i have and had the plugin activated, just loaded the (for me correctly displayed images), changed nothing and saved again with IV and tried again. and it seems to work
the uploads on my initial posting had been made via Windows Explorer (?) “Right Click” → “Rotate right” (“Nach Rechts drehen”)
You surprise me - Microsoft’s built in tool failing to follow standards and just bodging a result? [/sarcasm] Yeah - long ago avoided using that quick fix tool. Doesn’t surprise me getting buggy results.
Isn’t that “by default”? I’ve been using IrfanView as my goto flip, twist and resize tool for over a decade. That transform is installed by default as far as I can tell.
