PHPRunner deletes read-only files

I am storing images in a files directory.
I want the missing images to revert to showing a 'No Photo' image, so I have added an event to check whether the image filename is blank and if so, change it to none.gif
This works fine but there is one problem:

If the user uses the 'Delete' radio button, it deletes the none.gif file, even though I have set it to read-only.
Is there a good workaround to preserve the file when the user inadvertantly does this, and is this behaviour by design or a bug ?

Hi,
you can just rename none.gif to the no_image.gif.

That behaviour works when you are storing the image as a binary object within the database, but there is no attempt to display an image when storing images as files and the filename field is null.

Kevin,
for images saved on the disc use custom format on the "View as" settings dialog on the Visual Editor tab.

Here is a sample:

if (!$value)

$value = "<img src=\"images/none.gif\">";

Thanks for that.

It was slightly more complicated than that for me. I used this for my thumbnails (a virtual field) ...
if ($value=="th_")

$value = "<img src=\"files/images/th_none.gif\">";

else

$value = "<img src=\"files/images/".$value."\">";
... and ...
if ($value=="")

$value = "<img width=100 border=0 src=\"files/images/none.gif\">";

else

$value = "<img width=100 border=0 src=\"files/images/".$value."\">";
... for the actual photos in the View page, and 'Views' I created where I need printer-quality instead of the thumbnails.
(I'm sure you realised this sort of adaptation would be required, but it may be helpful to anyone else following this thread)
