Oh dear.
I reduce the size of my photos before uploading them because yes there is a file size limit. I don't need any other program to reduce photos because I do it on an image program.
However as I said before, some people's photos show up in the attachment and some people's like mine don't show in the attachment, and need to be clicked on, and I wondered why that is - and it seems to have nothing to do with the SIZE of the photo.
Also, try reducing a large 3 or 4Mb photo and it comes out blurred. I've discussed this with techie people and they all agree - either you take a not very clear photo and it will show up clear(er) on a forum but rubbish on your own pc, or vice versa, and everyone agrees what's on our own computers is what matters!
I don't need photo bucket or any of these things that open up C asino rubbish on my computer screen. I have my photos all filed and ordered on my pc and can upload direct to most forums that I use, and for the others I put photos on an online gallery.
