Can't Make Thumbnails

[jaredhales]

I am having trouble when trying to make thumbnails, I get the following errors:

Will converting from GD2 to ImageMagick solve this problem?

Will I need ghost script as well?

Will converting from GD2 to ImageMagick solve this problem?

Maybe (Maybe not )
Check your phpinfo()
Does it say something like:

GD Support enabled
GD Version 2.0 or higher

Does it show:

JPG Support enabled

Will I need ghost script as well?

Not "required". It provides routines used to support PDF functions. phpWCMS works fine w/o ghostscript

hello

did you test all possible settings in these few lines in the conf.inc.php?

Code: Select all

// other stuff
$phpwcms["compress_page"]     = 3;        //wenn 1 = Seite komprimieren, 0 = Kompresion aus
$phpwcms["imagick"]           = 0;        //if 0 = GD, 1 = ImageMagick convert, 2 = ImageMagick 4.2.9
$phpwcms["imagick_path"]      = "";       //Path to ImageMagick
$phpwcms["use_gd2"]           = 1;        //if 0 = GD1, 1 = GD2

[Oliver Georgi]

set
$phpwcms["use_gd2"] = 0; //if 0 = GD1, 1 = GD2

seems that you have support for GD1 only.

Switching to ImageMagick will solve such problems.
Bu you will need to have ImageMagick installed.

we don't have ImageMagick installed, but I might be able to get our sys admin to put it on the box.

How worthwhile will it be to push for that? What are the disadvantages to only running GD1?

And, will installing ImageMagick involve recompiling php? Or is this just a simple package that needs to be installed?

[jaredhales]

There doens't seem to be any mention of GD in my phpinfo()

also, i followed Oliver's advice and changed to:

Code: Select all

$phpwcms["use_gd2"]           = 0; //0 = GD1, 1 = GD2

however, i still get an error:

creating thumbnail! wait a moment!

Then you have no GD support enabled - tell your sysadmin.

[jaredhales]

so, what is required to install ImageMagick and get it working in phpwcms?

[Oliver Georgi]

ImageMagick

http://www.imagemagick.org

i have ImageMagick installed, and i am no longer getting as many errors. but, it is not working properly either. i am getting:

creating thumbnail! wait a moment!

no thumbnail exists

my config file is as follows:

Code: Select all

$phpwcms["imagick"]           = 1; //0 = GD,  1 = ImageMagick convert
$phpwcms["imagick_path"]      = "/usr/local/ImageMagick-5.5.7/bin/"; //Path to ImageMagick (default="" - none)

i checked the path and it appears to be correct, what's next?

[Oliver Georgi]

is it working when you try this in the shell anywhere:

Code: Select all

convert -version

Often better not to use full path to convert app.

Check folder permissions.

Oliver

[jaredhales]

Often better not to use full path to convert app.

What would you do instead? A relative path?

[Oliver Georgi]

...no path setting. Normally path to ImageMagick is available in global path var. That's why you should check "convert -version" anywhere on command line/shell.

my sysadmin got it working . . . woohoo!!!

now, osme of my old pictures have icnorrect thumbnails next to them (broken images). and the generate thumbnail button is gone. how do i redo the thumbnails now that it's working?

Trashcan those (they are just the " uniquely-named" thumbnails anyway) and re-upload/use FTP takeover.
