1000 pixels, that was 15 years ago? So my 6000 by 4000 images on Flickr are too big and I have to edit them just to upload them here?
No. If you are uploading an image from your computer, then it is suggested that you resize it to a 1000px on the long side, otherwise the forum will resize it to a much less quality of an image for you, which you will like even less than the suggested 1000 px long side thingie.
However, you may also link your image here from Flickr, then when someone clicks on it, it will take them right to the original Flickr image.
In Flickr, click the image you want to share, then click that arrow sign on the right hand side of your image. After that click "BBC Code" and click "original" on the drop down menu.
Now copy the code, and paste it here. This is what it will look like.
Keep in mind that if you click anything other then "original" it will not display the EXIF info here on the forum.
