As my portfolio builds I continue to see increases in DLs. I hit 62 on Wednesday plus an EL. I'm starting to see real improvements. Yesterday I deleted 7 images off my portfolio. Every since that moment not a single sale has been reported. True that Friday night and Saturday are slow but I've never seen zero in this time. Usually a half dozen anyway. I still find images of mine in searches. Is it just an unexpected lull? I perhaps need to get back on my anti-paranoia medication.

Go take your medicine.  LOL  I haven't had a sale in 2 days now, not that that is not normal for me as I still have a small portfolio.  But, I think you just have to expect a few slow days here and there.  BTW, I love your avatar, Green Crested Turacos are very pretty birds.  

How do you delete an image at SS?

You need to go to the submissions summaries and find the image. there is a X there which deletes the image

The nearer to summer you get the less sales you get at the weekends as the designers make the most of the good weather and take weekends off.
